move the chips to a considerable distance from the building, the chips 

 luid to be taken away by scrapers. When it is remembered that these 

 chips have slightly increased in weight in passing through the battery 

 the great expense of this proceeding is at once apparent. 



The percentage of water in the discharged chips was found to be as 

 follows: 



Since the mean of former experiments shows that sorghum contains 

 about 11 per cent fiber and matters insoluble in water, the composition 

 of the waste chips as indicated by the above determination is : 



Per cent. 



Fiber 11.00 



Water 88.10 



Other substances 90 



Total 100.00 



After passing the waste chips through the mill they had the follow- 

 ing per cent, of water : 



At 70 per cent, extraction the bagasse therefore contains one part 

 of fiber to two of water. By a short preliminary drying this bagasse 

 would readily burn. At any rate it presses so readily, requiring so lit- 

 tle power, that in my opinion, it would be a matter of economy to pass 

 it through a three-roll mill. 



The percentage of extraction obtained with the spent chips in small 

 experimental mill will be seen by the following numbers : 



The first column represents the per cents, calculated from weighing 

 the bagasse and the second from weighing the expressed water :
